I Application filed April 25, 1917. serial Ito. whim.

To all whom it may concern:

Be it known that I, Louis ARKIN, a. citizen of the United States of America, and resident of Boston, in the county of Sufiolk and State of Massachusetts, have invented new and useful Improvements in Fasteners, of which the following is a specification.

This invention relates to separable fasteners of the type commonly employed as a fastener for gloves, dresses, curtains, and the like, and comprising essentially complemental stud and socket members. More particularly the invention relates to the socket member of such fasteners.

In the fasteners of this general type heretofore provided, the socket member has studretaining means which are of necessity adapted and intended to grip the stud firmly enough to preclude accidental disengagement under the usual conditions of service. The stud is disengaged by a jerklor pull, and because of the essential firm grip of the retaining means such disengagement necessitates the application of considerable force so that light and delicate fabrics upon which these fasteners are commonly used are often torn and destroyed in the pulling or jerkw ing of the stud from the socket.

Again, in the use of these fasteners upon dresses or other clothing, not only is the material often in itself easily torn but the stud when engaged is located under the socket and often in a position not readily accessible to the wearer. It is therefore not infrequently a dificult matter to grasp the mate rial near enough to the stud to pull it from the socket without tearing the material even with the exercise of considerable care.

It is the principal object of this invention to provide a fastener wherein the stud while securely held under usual conditions of service can be readily disengaged from the socket without manipulation either of the stud itself or of the material to which the stud is secured.

Referring to the drawings which illustrate an embodiment of my invention,

Figure l is a top view of the socket partially broken away;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a side view of the socket;

P Fig. 4c is a section on the line H of Fig. 5 is a view similar to Fig. 2, but showing the stud within the socket.

Fig. 6 is a section on the line 6-6 of Fig. 1;

Figs. 7 and 8 are respectively side and top views showing alternative means for securing the fastener to the material;

Fig. 9 is a plan view of a spring plate;

Fig. 10 is a plan view of a base plate;

Fig. 11 is a plan view of a gromet; and

Fig. 12 is a plan View of a holding plate.

A is a metal casing of usual contour having a plurality of integral lugs (1 adapted to pass through slots 2') (Fig. 10) in the base plate B and thereafter to be turned over to secure said casing and plate. The said base plate has the usual stud receiving opening B, and when the fastener is to be used on clothing and the like. may be provided with apertures B (Fig. 8) for sewing the fastener to the material. When the fastener is to be attached to curtains and the like, the casing A is provided with a plurality of prongs A (Fig. 6) adapted to pass through slots 6 in the plate B and to be turned over upon the slotted groinet L disposed on the opposite side of the material.

Within said casing is a pear of springs C preferably made of wire which may be of any desired shape in cross section and having stud-retaining arms C spaced apart to provide oppositely disposed substantially wedge-shaped apertures ll), best shown in Fig. 4. Slidably mounted in the wall of the casing A and extending on both sides thereof, is a pair of stud-releasers 1E having substantially wedge-shaped heads movable within said apertures D to engage and spread said retaining arms C and release the stud as hereinafter described.

Within the casing A and above said springs C is a resilient member, preferably a spring plate F as shown, located in the path of the stud S and adapted to be engaged by the stud upon its insertion into the casing and to be stressed thereby, as clearly shown in Fig. 5. Between said plate F and said spring (3 is a stud-holding plate Gr having an aperture 9 into which the stud fits upon its insertion into the casing, and is thus held against tipping.

The stud S is of the form shown having an enlarged head S, said head being preferably flattened at the portion .9 which fits within the aperture 9 of the holding plate Gr.

When the stud S is inserted into the easing A through the stud aperture B, its head spreads and passes between the retaining arms G into and partially through the holding plate G engaging and lifting the spring F. When the stud head has passed therethrough, the retaining arms 0 close around the neck of the stud and said stud is thus firmly retained within the socket with theFspring F stressed thereby, as best shown in i 5.

To release the stud, the stud releasers E are simultaneously pressed inward, whereupon their wedge-shaped heads moving in the apertures D engage and spread the retaining arms C so that the stud head is free to pass therethrough, and the spring F being thus released jumps or forces the stud free of the socket. A

As the stud is released without manipulation thereof, it will be clear'that a socket member constructed in accordance with my invention above described permits the use of these fasteners upon the most delicate fabrics without danger of injury thereto upon disengagement of the fastener members. It will be equally clear that as the releasers E project beyond the casing and are thus read ily manipulated, the fastener can be disengaged without difiiculty even though it be secured to a dress or other article at a relatively inaccessible place.

A socket member of a fastener comprising a casing having a stud-receiving aperture, stud-retaining means Within said casing, stud releasers independent of said retaining means extending outside said casing and adapted to cooperate with said retaining means to release the stud and a resilient member adapted to force the stud from the socket without manipulation of said stud.
